2 GND Negative power terminal
Note:
First, dB is A pure unit of count: for power, dB = 10*lg(A/B). For voltage or current, dB = 20*lg(A/B). The meaning of dB is actually very simple, is to represent a number that is very large (followed by a long string of zeros) or very small (preceded by a long string of zeros) relatively short. Such as:
X=1000000000000000 (15 zeros in total)
It can be expressed as: 10lgX=150dB
X = 0.000000000000001
It can be expressed as: 10lgX=-150 dB
dBm is defined as miliwatt(milliwatt). 0 dBm=1mw;
dBw defines watt. 0 dBW = 10lg1 W = 10lg1000 mw = 30 dBm.
dB is always defined as a unit of power by default, measured in 10lg.
Of course, in some cases, the signal strength (Amplitude) can be used to describe the work and power, at this time, 20lg is used as a measure. This is true in both control and signal processing.
For example, sometimes you can see the expression dBmV.
